Abstract: A layout routing method includes determining a routing pattern according to a swapping rule, a via pattern, area constraints and pin locations; optimizing swapping in differential pairs according to the routing pattern; extracting features of each routing net to obtain extracted features; using an unsupervised algorithm to generate different routing groups according to the extracted features; and determining a routing order of the routing groups according to complex features of the routing groups.

Abstract: A method for performing automatic layout defect checking (ALDC) control regarding circuit design, associated apparatus and an associated computer-readable medium are provided. The method applicable to a processing circuit may include: providing a web-based entry in an ALDC control system running on a processing circuit, for any user among multiple users to upload at least a layout file of a package substrate design of at least one package substrate to the ALDC control system, in order to obtain at least the layout file from a client electronic device through the web-based entry; utilizing at least one backend program module to check the layout file according to a plurality of predetermined layout defect checking rules to generate at least one checking result, and create a layout defect checking report of the package substrate design; and sending the layout defect checking report corresponding to the layout file to the client electronic device.
